BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing a process sequence of a method for producing fertilizer using organic waste according to a preferred embodiment of the present invention. FIG.

The present invention relates to a fertilizer made using organic wastes such as animal manure, food wastes, and a method for producing the same.

Hereinafter, the present invention will be described in detail with reference to FIG. 1 showing an embodiment of the present invention, by dividing it into a fertilizer using organic waste and a fertilizer using organic waste.

[Fertilizers using organic waste]

In the present invention, 5 to 15 parts by weight of starch and 5 to 10 parts by weight of starch are mixed with 100 parts by weight of raw material mixture prepared by stirring and mixing 2 to 10 parts by weight of quicklime with 100 parts by weight of organic waste, The present invention relates to a fertilizer using organic waste.

That is, the fertilizer (hereinafter referred to as 'fertilizer') using organic wastes according to the present invention comprises a raw material mixture formed by mixing organic waste and quicklime macroscopically, starch mixed into the raw material mixture, and shell powder .

Specifically, organic wastes contained in the raw material mixture can be used as animal waste discharged from a general house, domestic animal wastes such as cows, pigs or chickens, food waste discharged from a home or a restaurant, and the organic wastes are not dried It is preferable to use water containing water.

In addition, when the organic waste is manure of livestock, a separate crushing process is not necessary since the animal manure generally comprises small fecal particles. However, when the organic waste is food waste, It is preferable to use an organic waste which has been subjected to the crushing treatment.

In addition, the quicklime contained in the raw material mixture removes the salt contained in the organic waste, evaporates and removes moisture contained in the organic waste by the heat generated in the hydration reaction of the quicklime, To kill various bacteria contained in the organic waste.

That is, the moisture contained in the organic waste is impregnated into the fine pores of the quicklime, and the calcium oxide (Ca (OH) ₂ ) and the calcium hydrogen carbonate (Ca (HCO ₃ ) ₂ ) And a large amount of reaction heat is generated.

[Reaction Scheme 1]

CaO + H ₂ O → Ca (OH) ₂ + 15.6 Kcal / mol

[Reaction Scheme 2]

_{Ca (OH) 2 + 2CO 2} → Ca (HCO 3) 2 + 35.4Kcal / mol

In addition, as shown in scheme 3 below are the ions contained in the calcium hydroxide and hydrogen carbonate of calcium, calcium ions (Ca ^{2 +)} and bicarbonate ion (HCO ₃ ^-) is a sodium ion (Na ^+), chloride ion (Cl ^-) and to each reaction, is converted into calcium chloride (CaCl ₂₎ and sodium hydrogen carbonate (NaHCO _3), wherein sodium (Na ^+, Cl ^-) is the effect which is immobilized in the calcium chloride (CaCl ₂₎ and sodium hydrogen carbonate (NaHCO ₃₎ .

[Reaction Scheme 3]

Ca ^{2 +} + HCO ₃ ^- + OH ^- + Na ⁺ + Cl ^- > CaCl ₂ + NaHCO ₃ + H ₂ O

The quicklime may be mixed with the organic waste at an appropriate mixing ratio to realize the above effect. Preferably, the quicklime is mixed at a mixing ratio of 2 to 10 parts by weight with respect to 100 parts by weight of the organic waste.

If the amount of the quicklime is less than 2 parts by weight based on 100 parts by weight of the organic waste, the composition of the quicklime is insufficient and there is a fear that the salt removal effect, the water evaporation effect and the bacteriostatic effect by the quicklime become insufficient, It is preferable that the quicklime is mixed with the organic waste at the mixing ratio within the above range because the composition of the quicklime is excessively mixed to cause the soil to be excessively alkalized by the quicklime remaining in the fertilizer.

In addition, it is preferable that the organic waste and quicklime are mixed with each other for the purpose of uniform mixing, and it is preferable that the organic waste and the quicklime are firstly dried during the stirring and mixing to evaporate a part of the water contained in the mixture (the waste cake described below) The dried mixture is subjected to secondary drying and disintegration to obtain organic wastes, solid calcium hydroxide (Ca (OH) ₂ ), calcium hydrogen carbonate (Ca (HCO ₃ ) ₂ ), calcium chloride (CaCl ₂ ) (NaHCO ₃ ) can be made into smaller particles.

Further, in the present invention, when the raw material mixture is prepared, the organic waste may contain balsam as well as burnt lime.

That is, the raw material mixture may be prepared by mixing 0.5 to 3 parts by weight of chestnut with 100 parts by weight of the organic waste, stirring and mixing, followed by drying and shredding.

Specifically, the bamboo shrub is a bark that surrounds the chestnut (bark) and is a natural product in which a large number of thorns appear on the outside. In general, it is a by-product that is discarded when harvesting chestnuts. It is known to contain a large amount of useful ingredients, but it is not easily decomposed because it has a lot of thorns and does not easily rot.

On the other hand, according to the present invention, when the organic waste and the quicklime are mixed with each other, the present invention can further mix the viscous organic wastes and the quicklime, which are formed on the outside of the chestnut, more uniformly, It is possible to further include an effective component of basshorn in the raw material mixture, thereby realizing the effect of improving the functionality of the basshut in the fertilizer according to the present invention.

In more detail, the chestnut is mixed and agitated when organic wastes and quicklime are mixed together, so that organic wastes and quicklime can be mixed more uniformly by a plurality of viscosities, and when the organic waste is mixed with the quicklime, It can be aged and softened as if it is stigmatized by heat generated by moisture and hydration reaction of quicklime.

In addition, as described above, the brittle softened tissue is further weakened in texture by the primary drying heat applied during the stirring mixing of the organic waste and quicklime and the secondary drying heat of the primary dried mixture, It is crushed at the time of crushing and is contained in the raw material mixture in a particle state.

In addition, the chestnut can be contained in the raw material mixture at an appropriate mixing ratio according to the judgment of a person skilled in the art, and preferably 0.5 to 3 parts by weight based on 100 parts by weight of the organic waste contained in the raw material mixture.

At this time, if the chestnut is contained in less than 0.5 part by weight with respect to 100 parts by weight of the organic waste, the chestnut is included in the raw material mixture to a lesser extent, The water contained in the organic waste may not be added smoothly to the production cycle and the hydration reaction may be slowed down during production. Therefore, it is preferable that the balsam is contained in the raw material mixture at the mixing ratio within the above range.

(C ₆ H ₁₀ O ₅ ) _n , wherein the glucose unit is an α-1,4 bond, and the starch has a molecular formula of (C ₆ H ₁₀ O ₅ ) _n , wherein the starch is mixed in an amount of 5 to 15 parts by weight based on 100 parts by weight of the raw material mixture. In the present invention, when the fertilizer is fertilized, the starch absorbs moisture to dissolve the granular (or pellet) fertilizer so that the fertilizer can be easily dissolved in the soil, .

At this time, the starch may be obtained from natural materials such as corn, potato, sweet potato or rice, and is preferably included in the fertilizer at a mixing ratio of 5 to 15 parts by weight based on 100 parts by weight of the raw material mixture.

That is, if the starch is contained in the fertilizer at less than 5 parts by weight with respect to 100 parts by weight of the raw material mixture, the mixing ratio of the starch is insufficient, and the effect of increasing the soundness of the fertilizer by the starch may be insufficient. , It is preferable that the starch retains the mixing ratio within the above range because the fertilizer may easily decay due to the degeneration of the starch due to moisture in the air.

In addition, in the present invention, when the fertilizer is fertilized, an oil component of the shell powder can be added to the fertilizer, and at the same time, the powder is mainly used as a particulate (or pellet) It is a constitution which makes the fertilizer made to be broken more easily by small size particle.

That is, the shell powder is composed mainly of calcium carbonate, and the calcium carbonate is presented as one of the components of the fertilizer generally used for increasing the force of the earth. In the present invention, the shell powder So that the aggregation of other compositions contained in the fertilizer particles can be more easily solved in the state that the fertilizer having the particulate (or pellet) is fertilized in the soil.

At this time, the shell powder may be obtained by pulverizing shells of one or more shellfish among general shellfish, and is preferably included in the fertilizer at a mixing ratio of 5 to 10 parts by weight based on 100 parts by weight of the raw material mixture.

If the shell powder is contained in less than 5 parts by weight with respect to 100 parts by weight of the raw material mixture, the blending ratio of the shell powder is insufficient, and the effect of increasing the crushability of the fertilizer particles by the shell powder may be insufficient. When the fertilizer is included in the fertilizer, the effect of improving the soil strength by the shell powder is excellent. However, there is a possibility that the fertilizer particles may be scattered before the fertilizer particles are crushed too much, so that the shell powder preferably maintains the mixing ratio within the above range .

In addition, in order to increase useful components of the fertilizer of the present invention, the functional mixture in which the pear juice solution and the peach seed powder are mixed may be further mixed in the raw material mixture.

In other words, the sap of the noodles is a kind of maple tree, which is absorbed during the night by the water of the night, and it flows out with increasing temperature in the daytime. It does not come out on the day when the weather is cloudy, rainy or windy, It is said that a lot comes out on a bad day.

In addition, the above-mentioned nodular sap solution contains a large amount of useful components such as sucrose and an inorganic substance, and is included in the fertilizer according to the present invention, so that the above-mentioned oil component can be contained in the soil.

In addition, since the nodular sap liquid has a certain viscosity, it is mixed with the mixture of the raw material mixture, the starch and the manure made of the shell powder to exert the effect of coating the outside of the mixture, The particles of the fertilizer are made into particulate or pelletized forms a certain cohesive force so that the formed fertilizer maintains a certain shape before fertilization and if water is added to the fertilizer after fertilization, It is possible to realize the effect that the coating layer can be easily dissolved in the water and that an oil component of the gourd liquid can be contained in the soil.

In addition, the above-mentioned peach seed powder has a constitution in which a fertilizer contains a useful component of peach seed, and contains a useful component of peach seed in the fertilizer according to the present invention.

That is, in general, peach seeds are the remaining seeds after obtaining the pulp from peaches to make processed foods such as peach drinks or canned foods, and peach seeds contain a large amount of cyanoglycosides which can be harmful to the human body by overdosing, It is known that ingestion can lead to poisoning.

Therefore, the present invention can realize the effect of utilizing the peach seed which is generally disposed of as a useful component of fertilizer. Further, a detailed description of the useful components of the peach seeds will be made by a known technique.

In connection with the above, the peach seed powder is prepared by crushing the peach seed into an appropriate size, and the size of the powder particle can be appropriately adjusted according to the judgment of a person skilled in the art.

The peach seed powder may be directly mixed with the raw material mixture. Preferably, 10 to 30 parts by weight of the peach seed powder is mixed with 100 parts by weight of the pine nut solution, And may be mixed with the raw material mixture into the liquid.

That is, if the peach seed powder is contained in the functional liquid at less than 10 parts by weight with respect to 100 parts by weight of the gonad juice solution, the effect of containing the useful ingredient by the peach seed is somewhat insufficient, and if it exceeds 30 parts by weight, However, since the mixing ratio of the peach seed powder to the gonad juice is relatively high, the functional liquid is smoothly adhered to the outside of the mixture contained in the raw material mixture and is not coated, so that the peach seed powder It is preferable to maintain the mixing ratio.

It is preferable that the functional liquid having the above composition is contained at a mixing ratio of 3 to 10 parts by weight based on 100 parts by weight of the raw material mixture. If the functional liquid is contained in an amount of less than 3 parts by weight based on the raw material mixture, When the amount of the functional liquid is more than 10 parts by weight, it takes a long time to dry the moisture contained in the functional liquid having the liquid phase, which lowers the economical efficiency. Therefore, the functional liquid is preferably mixed with the raw material mixture at the mixing ratio within the above range.

Also, as described above, the fertilizer formed by mixing the raw material mixture and the functional liquid with stirring is contained in a certain amount of water due to the moisture of the nodule liquid contained in the functional liquid. In the present invention, the functional liquid is mixed with the raw material mixture If it is further contained, it is preferable to carry out further drying treatment to evaporate water contained in the fertilizer.

At this time, when the raw material mixture containing the functional liquid is heated to an excessively high temperature, the oil component contained in the liquid of the nacreous liquid disappears together with the evaporated moisture, so that the raw material mixture containing the functional liquid is heated It is preferable to evaporate water contained in the fertilizer, and the water content of the heated and dried fertilizer can be appropriately adjusted according to the use of the fertilizer according to the judgment of a person skilled in the art.

[Manufacturing method of fertilizer using organic waste]

The present invention relates to a waste cake producing process (S100) in which 2 to 10 parts by weight of quicklime is mixed with 100 parts by weight of organic waste by stirring and dried to produce a waste cake; A drying step (S200) of drying the waste cake; A raw material mixture producing step (S300) of making the raw material mixture by crushing the waste cake treated in the drying step (S200); And a fertilizer producing step (S400) for producing a fertilizer by stirring 5 to 15 parts by weight of starch and 5 to 10 parts by weight of shell powder with respect to 100 parts by weight of the raw material mixture (S400). will be.

At this time, the function and mixing ratio of the chestnut will be replaced with a specific description of the fertilizer.

The drying step (S200) is a process of drying the waste cake obtained in the waste cake forming process (S100), and drying the moisture remaining in the waste cake.

That is, in the drying step (S200), the waste cake is treated using a dryer supplied through a belt conveyor or a screw conveyor from an agitator performing the waste cake forming process (S100), and the dryer is heated And the inside of the chamber can be heated to a temperature.

If the heating temperature of the dryer is less than 120 ° C., the drying time of the moisture contained in the waste cake is excessively required, which lowers productivity. If the drying temperature exceeds 195 ° C., the waste cake may be carbonized by excessively applied drying heat. The heating temperature of the dryer is preferably kept within the above range.

In this connection, the dryer may be provided with a steam outlet for discharging the moisture in the steam generated in the chamber to the outside, and the steam discharged to the outside through the steam outlet is condensed after passing through the cooling device It can be made of liquid fertilizer (liquid fertilizer).

In this case, the liquid fertilizer may include a useful ingredient by the organic waste and the sludge (in the waste cake producing process (S100), the liquid fertilizer may further include a useful ingredient of the chestnut tree when the chestnut is further mixed) As a fertilizer, it can be used as a fertilizer separate from the fertilizer according to the present invention.

In addition, the raw material mixture producing step (S300) is a process of making a raw material mixture by crushing the waste cake treated in the drying process (S200), and making the waste cake dried through the drying process (S200) into a particulate state.

More specifically, the raw material mixture producing step (S300) is a step of reducing the particle size of the waste cake by injecting the waste cake, which is dried in the drying step (S200), into the crusher, (S300) can be performed through the crusher.

In addition, the average particle size of the raw material mixture formed by crushing the waste cake in the raw material mixture producing step (S300) can be appropriately adjusted according to the form of the fertilizer to be produced.

At this time, the raw material mixture formed by crushing in the crusher of the raw material mixture producing step (S300) may be further transferred to the vibrator provided separately, and then the particles of the raw material mixture may be further separated from the vibrator. Alternatively, A dispersant that allows the prepared fertilizer to be more easily dispersed in the soil when the fertilizer is fertilized, a filler that can prevent the scattering of the fertilizer by increasing the specific gravity of the fertilizer, or a neutralizer that can alleviate the odor of the fertilizer .

Further, when the prepared fertilizer is made into the form of pellets, it is possible to further mix the binder so that the raw material mixture particles can be more easily aggregated in the form of pellets in the raw material mixture further separated from the particles in the vibrator.

In the fertilizer production step (S400), 5 to 15 parts by weight of starch and 5 to 10 parts by weight of shell powder are mixed with 100 parts by weight of the raw material mixture produced in the raw material mixture producing step (S300) , And starch and shell powder are mixed with the raw material mixture.
